## Technical details

The plugin contains a SQL injection vulnerability (CWE-89) in an AJAX action that does not properly sanitize or escape user-supplied parameters before using them in database queries. The vulnerable endpoint is accessible to unauthenticated users, lowering the barrier to exploitation. An attacker can craft a malicious HTTP request containing SQL metacharacters in the product parameter to break out of the intended query and execute arbitrary SQL commands. This allows extraction of sensitive data from the WordPress database. No patch is currently available as of the advisory date.
